46 percent preferred Democrats and 42 percent preferred Republicans in a generic ballot for the House of Representatives.

51 percent of voters said they would prefer that Democrats get elected as a check against Trump; 39 percent said they would prefer that Republicans get elected.

When voters were asked if were excited about the midterm elections, 78 percent of those who voted for Hillary Clinton said they were excited about the elections, compared to 64 percent of those who voted for Trump said they were excited.

"The leanings of undecided voters and the preference for more Democrats to be a check on Trump both show that Trump is a lead weight for Republicans," the PAC's memo read, according to The Hill.

The Priorities USA survey was conducted among 1,001 people who voted during the presidential year, and was conducted Feb. 2 to Feb. 7. The survey has a margin of error of 3.1 percentage points, the report said.

A poll conducted by Politico and Morning Consult also showed rising approval for the president.
